Abstract
Apparatus for testing System-In-Package (SIP) devices each having a plurality of electrical leads is described. The apparatus utilizes industry standard JEDEC trays and tests at least a predetermined portion of all devices in such trays at the same time. The apparatus comprises a test hive comprising: a plurality of test circuits corresponding in number to at least a predetermined number of cells in the tray; and a plurality of groups of test contacts, each group is coupled to one of the test circuits and is oriented to engage the plurality of electrical contacts of a SIP device disposed in a corresponding one of the cells. The test hive is operable to simultaneously, electrically test at least a predetermined number of the number of the SIP devices in each tray engaged by the hive without removing the SIP devices from the tray. The apparatus also includes a sorter automatically operable to remove each SIP device that did not pass electrical testing with SIP devices that did pass electrical testing until a tray of electrically tested SIP devices is fully populated with SIP devices that did pass electrical testing.
